I just read that the 2010 engine technology using DEF has surpassed all expectations and they are doing about 20% above what was expected. The trucks now are 60 times cleaner then a 1988 model and they are getting at least 5% better fuel mileage. Now with the GHG14 standards (Green House Gas), we are within sight of seeing a 10mpg 80,000lb truck. Over 9mpg is being seen with the new trucks-so the technology is working. Yes there are mishaps that cost money, but this is why we're strongly suggesting all new truck and bus buyers to get extra warranties. With the maximum 5yr/500,000mi Vehicle, 5yr/500,000mi Detroit EW4, and 5 year extended warranty tow, that will cost about $11,300.00 extra. Sounds like alot? Divide $11,300.00 by 500,000mi and it costs you 2.26 cents/mile! When I was driving, I used 10 cents a mile for maintenance as a rule of thumb. Good Luck, TomC

The reason a Honda Fit or a Toyota Eco gets such good mileage and low emissions is because decades of racing experience have showed them how to make engines of extremely high volumetric efficiency.....this is how you win races...

The same ideas.....applied to highway cars.....make for smaller engines.....lighter weights...better aero efficiency....and much more.... so.....racing his the PRIMARY factor in the efficiency of the modern car.....NOT some silly government stooge telling engineers how to build stuff.....period...

.....NOT some silly government stooge telling engineers how to build stuff.....period...

As Belfert correctly pointed out before, the Government doesn't tell engineers HOW to build stuff - it limits what can and cannot be built - and that's a good thing, because without limits engineers inevitably get their priorities all screwed up.

The best form of regulation is always through the market, but the market (and society in general) very often needs to be led in the right direction, and a major part of the Government's purpose is to do that leading. Think about vehicle safety for example - car manufacturers didn't start fitting seatbelts because the market demanded them - they started fitting them because of legislation. But now the market has followed that lead and safety generally is a big selling factor - for instance airbags aren't required by legislation, but they are demanded by the market.

It's not about personal egos, it's about common sense - would you really rather the Government not lead food producers (for example) in what they can and cannot sell to the consumer? Being led on the type of issues we're talking about here is necessary and healthy for individuals and society - it's not about giving up your free will or being emasculated in any way. Although idiot organ donors motorcyclists who insist on their right not wear helmets might disagree I suppose.

It is rather simple....either you own yourself and what you produce...or you do NOT...

And...if you do not... Who does? And...doesn't that make you a slave?

There is another answer...there should be noone in a Government suit that can tell a food producer what to produce or how to do so...

But...there should be a number of Guilds and Associations that have their own set of rules that their members must use...if you want someone else to do you due diligence for you...pick the Guild that suits your level of concern...

There should NOT be someone sitting there using their power to say "NO...you can't start that business there...or that way...or without being rich enough...or all of the other ways that Government gets in the way....

Look at aviation...the homebuilt airplane market is the only part of the General Aviation market that is growing... Why? Because it costs MILLIONS to get the silly piece of paper from the FAA you need to sell your new design as a complete airplane... Of course you can sell it as a kit...but that cuts your potential market to those technically capable of building an airplane...and that also have the time and money.....

The helmet laws you speak of are a perfect example...I, personally, as a retired motorcycle roadracer (someone that has hit the ground at 162mph) and crewchief will not ride a motorcycle across a parking lot without full racing gear...but if someone is stupid enough to want to ride their Yamaha R1 175mph totally naked.....NOT MY BUSINESS.....or yours...
